Greetings! Trying to determine what was the correct fasteners used that secures the box on the top of the fire wall in the engine compartment...I have the flat washer and star washer but the nuts are almost nonexistent:-/ I can see the fine threaded studs, but were they regular nuts, flange nuts, etc...I searched a few pics online and was hard to make them out...thank you in advance.
Regards,
Noah
